NO.PZ202206140600000202问题如下 Baseon the client’s investment mante, the most appropriate appraismeasure for McNeil to use is the:A.Sortino ratio.B.Treynor ratio.C.information ratio.SolutionA is correct. Given ththe funmante requirement is for a short-term return in excess of the risk-free rate, the Sortino ratio is a more appropriate measure because it penalizes returns below a specific return—in this case, 1.5% above the risk-free rate. B is incorrect. The Treynor ratio penalizes returns below the risk-free rate. It will not measure the funs ability to meet the requirement of a short-term return in excess of the risk-free rate.C is incorrect. The information ratio evaluates the portfolio return relative to a benchmark. It will not measure the funs ability to meet the requirement of a short-term return in excess of the risk-free rate.Treynor就是目标回报减去无风险利率的回报，不是正好可以用来衡量题目中的特征要求么
